Researching the researchers   p417
doi:10.1038/ng.2972
Francis Collins, director of the US National Institutes of Health, recently highlighted in Nature the need to identify and correct systematic problems in biomedical research. One such effort, the Stanford Meta-Research Innovation Center, will monitor the practice of research and suggest policies for improvement. We commend this initiative that supports our commitment to publishing scientifically rigorous research.

MDA5 and autoimmune disease   pp418 - 419
Jonathan J Miner & Michael S Diamond
doi:10.1038/ng.2959
A new study shows that gain-of-function mutations in IFIH1, which encodes the cytosolic double-stranded RNA sensor MDA5, lead to upregulated type I interferon responses. Individuals with these mutations exhibit phenotypes consistent with autoimmune diseases, including Aicardi-Goutieres syndrome and systemic lupus erythematosus.

TDP2 keeps the brain healthy   pp419 - 421
Peter J McKinnon
doi:10.1038/ng.2967
Many inherited human DNA repair deficiency syndromes involve pronounced neurological dysfunction, although the DNA lesions responsible are generally unknown. A new study shows that the phosphodiesterase TDP2 has a key role in protecting the nervous system by preventing DNA breaks induced by aberrant topoisomerase II activity.

ACVR1 mutations and the genomic landscape of pediatric diffuse glioma   pp421 - 422
Gelareh Zadeh & Kenneth Aldape
doi:10.1038/ng.2970
Pediatric diffuse gliomas are rare but aggressive brain tumors for which effective therapies are unavailable. New studies identify recurrent mutations of the ACVR1 gene in these tumors, identify molecular subtypes and highlight differences between gliomas affecting children and adults.

Recurrent SMARCA4 mutations in small cell carcinoma of the ovary   pp424 - 426
Petar Jelinic, Jennifer J Mueller, Narciso Olvera, Fanny Dao, Sasinya N Scott, Ronak Shah, JianJiong Gao, Nikolaus Schultz, Mithat Gonen, Robert A Soslow, Michael F Berger & Douglas A Levine
doi:10.1038/ng.2922
Douglas Levine and colleagues identify recurrent inactivating mutations in the SWI/SNF complex member SMARCA4 in 12 of 12 samples of small cell carcinoma of the ovary, hypercalcemic type. These findings open the door for the development of targeted therapies to treat this rare but deadly cancer.

Small cell carcinoma of the ovary, hypercalcemic type, displays frequent inactivating germline and somatic mutations in SMARCA4   pp427 - 429
Pilar Ramos, Anthony N Karnezis, David W Craig, Aleksandar Sekulic, Megan L Russell, William P D Hendricks, Jason J Corneveaux, Michael T Barrett, Karey Shumansky, Yidong Yang, Sohrab P Shah, Leah M Prentice, Marco A Marra, Jeffrey Kiefer, Victoria L Zismann, Troy A McEachron, Bodour Salhia, Jaime Prat, Emanuela D'Angelo, Blaise A Clarke, Joseph G Pressey, John H Farley, Stephen P Anthony, Richard B S Roden, Heather E Cunliffe, David G Huntsman & Jeffrey M Trent
doi:10.1038/ng.2928
Jeffrey Trent, David Huntsman and colleagues identify the SWI/SNF chromatin-remodeling gene SMARCA4 as commonly mutated in small cell carcinoma of the ovary, hypercalcemic type (SCCOHT). Their results implicate SMARCA4 as a crucial factor in the oncogenesis of SCCOHT, a rare but highly malignant cancer.

doi:10.1038/ng.2951
Fred Wright, Patrick Sullivan and colleagues present the results of a large expression QTL study of peripheral blood using a classic twin design with follow-up replication in independent samples. Their results enable a more precise estimate of the heritability of gene expression and provide a useful resource for exploring the genetic control of transcription.

Germline and somatic SMARCA4 mutations characterize small cell carcinoma of the ovary, hypercalcemic type   pp438 - 443
Leora Witkowski, Jian Carrot-Zhang, Steffen Albrecht, Somayyeh Fahiminiya, Nancy Hamel, Eva Tomiak, David Grynspan, Emmanouil Saloustros, Javad Nadaf, Barbara Rivera, Catherine Gilpin, Ester Castellsagué, Rachel Silva-Smith, François Plourde, Mona Wu, Avi Saskin, Madeleine Arseneault, Rouzan G Karabakhtsian, Elizabeth A Reilly, Frederick R Ueland, Anna Margiolaki, Kitty Pavlakis, Sharon M Castellino, Janez Lamovec, Helen J Mackay, Lawrence M Roth, Thomas M Ulbright, Tracey A Bender, Vassilis Georgoulias, Michel Longy, Andrew Berchuck, Marc Tischkowitz, Inga Nagel, Reiner Siebert, Colin J R Stewart, Jocelyne Arseneau, W Glenn McCluggage, Blaise A Clarke, Yasser Riazalhosseini, Martin Hasselblatt, Jacek Majewski & William D Foulkes
doi:10.1038/ng.2931
William Foulkes and colleagues identify germline inactivating mutations in familial cases of small cell carcinoma of the ovary, hypercalcemic type (SCCOHT). Through additional analysis of non-familial tumors, the authors find that nearly 100% of tumors carry SMARCA4 mutations and 38 of 40 lack protein expression, implicating SMARCA4 loss as the major cause of SCCOHT.

The genomic landscape of diffuse intrinsic pontine glioma and pediatric non-brainstem high-grade glioma   pp444 - 450

GRM1 is upregulated through gene fusion and promoter swapping in chondromyxoid fibroma   pp474 - 477
Karolin H Nord, Henrik Lilljebjörn, Francesco Vezzi, Jenny Nilsson, Linda Magnusson, Johnbosco Tayebwa, Danielle de Jong, Judith V M G Bovée, Pancras C W Hogendoorn & Karoly Szuhai
doi:10.1038/ng.2927
Karolin Nord and colleagues report that GRM1 recombines with multiple genes in promoter swapping and gene fusion events in 90% of the chondromyxoid fibroma cases analyzed, resulting in GRM1 overexpression. These results implicate GRM1 rearrangement as a driver of CMF and a biomarker for this tumor type.

POT1 loss-of-function variants predispose to familial melanoma   pp478 - 481
Carla Daniela Robles-Espinoza, Mark Harland, Andrew J Ramsay, Lauren G Aoude, Víctor Quesada, Zhihao Ding, Karen A Pooley, Antonia L Pritchard, Jessamy C Tiffen, Mia Petljak, Jane M Palmer, Judith Symmons, Peter Johansson, Mitchell S Stark, Michael G Gartside, Helen Snowden, Grant W Montgomery, Nicholas G Martin, Jimmy Z Liu, Jiyeon Choi, Matthew Makowski, Kevin M Brown, Alison M Dunning, Thomas M Keane, Carlos López-Otín, Nelleke A Gruis, Nicholas K Hayward, D Timothy Bishop, Julia A Newton-Bishop & David J Adams
doi:10.1038/ng.2947
David Adams, Julia Newton-Bishop, Timothy Bishop, Nicholas Hayward and colleagues identify loss-of-function variants in POT1 in several families with early onset multiple primary melanoma. They further show that these variants disrupt telomere binding by POT1 and are associated with increased telomere length.

doi:10.1038/ng.2941
Maria Teresa Landi and colleagues identify a rare missense variant in POT1 shared by five melanoma-prone families from Italy and associated with increased telomere length and telomere fragility. They also identify additional familial melanoma cases with rare missense variants in POT1 and find a significant excess of rare exonic POT1 variants in melanoma cases compared to controls, implicating POT1 variants in melanoma susceptibility.

doi:10.1038/ng.2948
Eamonn Sheridan, Elizabeth Ross and colleagues report discovery of a new megalencephaly syndrome caused by de novo missense mutations in CCND2. They show that these mutations lead to stabilization of cyclin D2, and they present evidence that cyclin D2 stabilization may be a common downstream mechanism in PI3K-AKT-associated megalencephaly syndromes.

TDP2 protects transcription from abortive topoisomerase activity and is required for normal neural function   pp516 - 521
Fernando Gómez-Herreros, Janneke H M Schuurs-Hoeijmakers, Mark McCormack, Marie T Greally, Stuart Rulten, Rocío Romero-Granados, Timothy J Counihan, Elijah Chaila, Judith Conroy, Sean Ennis, Norman Delanty, Felipe Cortés-Ledesma, Arjan P M de Brouwer, Gianpiero L Cavalleri, Sherif F El-Khamisy, Bert B A de Vries & Keith W Caldecott
doi:10.1038/ng.2929
Keith Caldecott, Bert de Vries, Sherif El-Khamisy, Gianpiero Cavalleri and colleagues identify homozygous TDP2 mutations in individuals with intellectual disability, seizures and ataxia. Their follow-up studies suggest that TDP2 is required to maintain normal transcription in response to the DNA double-strand breaks induced by abortive TOP2 activity.
